Can't upgrade on UnifiOS 1.37.11 NO_PUBKEY

I'm running on 1.37.10 on UnifiOS and if I follow the Wiki steps to upgrade, I'm getting this error. I've tried upgrading before since initial install and it's always the same error.

I found this on Git, but it's not my exact scenario.

  • Could you try:

    podman exec unifi-os cat /etc/apt/sources.list.d/nextdns.list
    podman exec unifi-os ls -l /usr/share/keyrings/nextdns.gpg
  • My device doesn't have podman installed.

    • Ryan H OK, my bad. I don't know why you have the right line in `/etc/apt/sources.list.d`, but not the GPG key. You can run:

      (wget -qO /usr/share/keyrings/nextdns.gpg https://repo.nextdns.io/nextdns.gpg ||  curl -sfL https://repo.nextdns.io/nextdns.gpg -o /usr/share/keyrings/nextdns.gpg) &&  chmod 0644 /usr/share/keyrings/nextdns.gpg

      Then, the upgrade should work. Maybe something failed with an older version of the install script.

  • Thank you Vincent, that worked. I'm now on the latest version.
